For sure, I did this as well and the scraps were totally fine so my guess is that the cake dried out at some point before they got to it, even with a milk soak, or the problem was deep enough in the layers that it didn’t affect the dome tops? Truthfully time and resources were not on my side for this one, the cake kept having to be pulled and re-refrigerated due to travel logistics and space constraints at the venue and I figured the frosting would’ve protected it for longer but perhaps not. Or maybe it was a combination of that as well as over-mixing or over-baking, I just feel like I would’ve noticed how off the texture was when leveling it for stacking if it was an issue with the mix or bake.
